The CU Medical CU-SP1 defibrillator automatically analyzes the electrocardiogram through the electrode pads and detects ventricular fibrillation or ventricular tachycardia. When it detects a shockable rhythm, it charges automatically and delivers an electric shock when the SHOCK button is pressed. It guides the rescue process with voice prompts, LED indicators, and graphical indicators, detects ambient noise, and includes a CPR guide.

The internal memory stores up to 5 rescue events, with recordings of up to 3 hours. Data can be transferred to a computer via IrDA or from the internal memory to an SD card. It is suitable for use on ships and in public spaces outside hospital settings.
